Description

Technical field of the invention

The disclosure relates to the field of shoes, in particular to leather shoes with elasticity and waterproof performance and a manufacturing method thereof. The application is based on the Chinese invention patent application No. 200910041801.1 submitted in Aug. 11, 2009, and all disclosed contents will be included in the text by reference.

Background of the invention

Leather shoes are common articles in people's daily life. Traditional leather shoes made fully of leather not only have graceful texture, but also show the status of the user; besides, as the insides thereof are made of genuine leather, moisture of feet can be absorbed, consequently, no smell is generated after long-term use.
In the conventional art, as the soles of the traditional leather shoes are usually made of stiff leather, the soles are lack of elasticity and poor in softness , the user may easily have foot fatigue when walking with such shoes, much more seriously, if the user walks for a long period with such shoes, calluses, dead skins or foot fatigue and the like may be generated easily due to long-term pressure and friction of the leather shoes on feet, which seriously affects the comfort of wearing the leather shoes of the user. In addition, the traditional full-leather shoes have no waterproof function, in moist or rainy days, the insides of the shoes become moist and the user may feel uncomfortable as the uppers and soles of the leather shoes absorb moisture, besides, the leather fiber deforms and becomes floppy easily after the leather shoes contact water, the wearable performance and adhesion strength of the leather shoes will decrease greatly, it is easy to cause the soles of the full-leather shoes to separate off the shoes or accelerate the abrasion of the leather shoes, to seriously affect the outside appearance of the leather shoes. Above defects limit the application occasions of the full-leather shoes, the demand of customers to wear and enjoy leather shoes for a long time no matter in which place and at which time cannot be met, which is undoubtedly a kind of waste for both manufacturers and customers.
Chinese patent ZL 96204675.2 disclosed "SOFT LEATHER SHOES WITH AUXILIARY ELASTICITY", the technical solution of the patent is that an auxiliary elastic layer is arranged in the front part inside the soles, a comfortable layer is arranged at the lower end of the inner gasket, the comfortable layer and the auxiliary elastic layer are made of soft materials such as foam plastics, sponge and rubber, in this way, the comfort of feet can be increased, and the soles can be more soft. Although the softness of leather shoes can be improved to some extent through this patent, the technical solution of the patent mainly improves the softness of the soles, instead of realizing the comfort and softness of the whole structure of leather shoes and meeting the demands of customers for application in various occasions. In addition, only depending on the auxiliary elastic layer and the comfortable layer, without considering factors such as humanized design and human mechanics, the patent cannot solve the demands of customers for comfort at all.
Chinese patent ZL 01125258.8 disclosed "WATERPROOF SHOES AND MANUFACTURING METHOD THEREOF", the feature of the waterproof shoes is that an inner waterproof sleeve is arranged inside shoes, and the inner waterproof sleeve is permeable to air but not to water. However, although the inner waterproof sleeve of the waterproof shoes has the waterproof function, the inner waterproof sleeve thereof may cause the user to feel uncomfortable when the user wears the waterproof shoes, therefore the demands of customers for comfort cannot be met at all.
Therefore, in allusion to defects of the conventional art, it is necessary to provide waterproof anti-deformation comfortable and graceful leather shoes and a manufacturing method thereof.
